pIII cpu and why it was over clocked

[dirtfarmer]

first off i had fun with my computer it would crash sometime that even the BIOS would not run nothing it happen a 3 time a dealer thought it was a motherborad but end up replaceing the chip a 433 Mhz to a pIII 800 Mhz or what was suppose to be a 800 Mhz, i look in the bios he has it over clock by 100-> 133 Mhz to make it a 800 Mhz, if the overclock was disabled it a a 600 Mhz, now that not normal is it ??????????? to over clock by 200 Mhz, so it not ready a 800 cpu is it ????????? i got short change i feel maybe and maybe not ????????

a side question it a cpu stop work for any reason, could you still get in to bios, as my computer when it stop it all stop i got nothing no sound or window no bios nothing, and ontil now no one fique it out maybe so is a cpu connect to the bios in any way

There are PIIIs that do run at 133MHz...the 800Mhz is one of the chips that has two versions, one has a multiplier of 8 and runs on a 100Mhz bus, the other has a multiplier of 6 and runs on a 133MHz bus. If it has the designation of 800EB then it is the 133Mhz version and it should run at that speed, and if your mother board supports that bus speed then all your peripherals will run at the correct speed. By changing it(bus speed) to 100MHz you are actually "under-clocking" the chip...
